These quotes were mentioned in Terry Hansen’s book, The Missing Times – News Media Complicity in the UFO Cover-up.

“CHAPTER ONE: Project Blue Book and the UFO Story.13”

“Our policy on releasing information was to answer only direct questions from the press. If the press didn’t know about a given UFO incident, they naturally couldn’t ask questions about it. Consequently such stories were never released. In other instances, when the particulars of a UFO sighting were released, they were only the bare facts about what was reported. Any additional information that might have been developed during later investigations and analyses was not released.”

“…, I knew that this was absurd because any ham radio operator worth his salt could build equipment and listen in on any intercept. The real reason for the press dismissal, I learned, was that not a few people in the radar room were positive that this night would be the big night in UFO history – the night when a pilot would close in on and get a good look at a UFO and they didn’t want the press to be in on it.”
